The invention relates to new substituted triazolinones, several processes for their preparation and their use as herbicides and plant growth regulators.

It is known that certain nitrogen-heterocyclics such as, for example, imidazolidin-2-one-1-carboxylic acid isobutylamide (compare, for example, K.H. Buchel "Pflanzenschutz und Schadlingsbekampfung" ("Plant Protection and Pest Control") p. 170, Thieme Verlag Stuttgart 1977) or 1-phenyl-3-(3-trifluoromethylphenyl)-5-methyl-perhydropyrimidin-2-one (compare, for example, European Patent 58,868 or DE-OS (German Published Specification) 3,237,479) have herbicidal properties. However, the herbicidal activity of these already known compounds against problem weeds, like their tolerance towards important crop plants, is not always completely satisfactory in all fields of use.

Certain substituted triazolinones, such as, for example, 1-(N,N-dimethylcarbamoyl)-3-isopropylthio-4-methyl -1,2,4-triazoline-5-thione, 1-(N,N-dimethylcarbamoyl)-3-ethylthio-4-methyl-1,2,4-triazoline-5-thione, 1-(N,N-dimethylcarbamoyl)-3-isopropylthio-4-methyl-1,2,4-triazolin-5-one, 1-(N,N-dimethylcarbamoyl)-3-ethylthio-4-methyl-1,2,4-triazolin-5-one, 1-(N,N-dimethylcarbamoyl)-3-methylthio-4-methyl-1,2,4-triazolin-5-one, 1-(N,N-dimethylcarbamoyl)-3-propylthio-4-methyl-1,2,4-triazoline-5-thione, 1-(N,N-dimethylcarbamoyl)-3-allylthio-4-methyl-1,2,4-triazoline-5-thione and 1-(N,N-dimethylcarbamoyt)-3-methylthio-4-methyl-1,Z,4-triazoline-5-thione, are furthermore known (compare DE-OS (German Published Specification) 2,707,801). Nothing is as yet known of an activity of these already known triazolinones as herbicides or plant growth regulators.

It is also known that certain substituted aminocarbonylimidazolinones, such as, for example, 1-isobutyl-aminocarbonyl-2-imidazolidinone (isocarbamid), have herbicidal properties (cf. R. Wegler, Chemie der Pflanzenschutz-und und Schadlingsbekampfungsmittel Chemistry of Plant Protection Agents and Pesticides!, Volume 5, p. 219, Springer-Verlag, Berlin-Heidelberg-New York, 1977). However, the action of this compound is not satisfactory in all respects.

New substituted triazolinones of the general formula (I) ##STR2## in which R¹ represents hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, halogenoalkinyl, alkoxyalkyl, alkoxy, cycloalkylalkyl or cycloalkyl, or represents in each case optionally substituted aralkyl or aryl,

R2 represents a radical ##STR3## or represents a radical --S(O)_(n) -R⁷,

R³ and R4 independently of one another each represent hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, halogenoalkinyl, cyanoalkyl, hydroxyalkyl, alkoxyalkyl, alkyl-aminoalkyl, alkoxycarbonylalkyl or alkoxycarbonyl-alkenyl, or represent in each case optionally substituted cycloalkyl, cycloalkylalkyl, cyclo-alkenyl or cycloalkenylalkyl, or represent option-ally substituted heterocyclylalkyl, or represent in each case optionally substituted aralkyl, aroyl or aryl, or represent alkoxy, alkenyloxy, alkinyloxy, aralkyloxy or aryloxy, or, together with the nitrogen atom to which they are bonded, represent an optionally substituted heterocyclic radical,

X represents oxygen or sulphur and

Y represents oxygen or sulphur,

wherein

R⁵ and R⁶ independently of one another each represent alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, halogenoalkinyl, alkoxyalkyl, alkoxy, cycloatkyl or cycloalkylalkyl, or represent in each case optionally substituted aryl, aralkyl or heteroaryl, or, together with the nitrogen atom to which they are bonded, represent an optionally substituted heterocyclic radical, R⁷ represents alkyl, alkenyl, alkinyl, cycloalkyl or cycloalkylalkyl, or represents in each case optionally substituted aralkyl or aryl and n represents the number 0, 1 or 2, but wherein R² only represents a radical --S(O)_(n) --R⁷ if R³ and R⁴ do not simultaneously represent methyl, have been found.

It has furthermore been found that the new substituted triazolinones of the general formula (I) ##STR4## in which R¹, R², R³, R⁴, X and Y have the abovementioned meaning, are obtained by a process in which

a) 1-chloro-(thio)-carbonyltriazolinones of the formula (II) ##STR5## in which R¹, R², X and Y have the abovementioned meaning, are reacted with amines of the formula (III) ##STR6## in which R³ and R⁴ have the abovementioned meaning, if appropriate in the presence of a diluent and if appropriate in the presence of an acid-binding agent, or

b) in the case where R³ denotes hydrogen, by a process in which triazolinones unsubstituted in the 1-position, of the formula (IV) ##STR7## in which R¹, R² and X have the abovementioned meaning, are reacted with iso(thio)cyanates of the formula (V)

    R.sup.4 --N═C═Y                                    (V)

in which

R⁴ and Y have the abovementioned meaning, if appropriate in the presence of a diluent and if appropriate in the presence of a reaction auxiliary.

Finally, it has been found that the new substituted triazolinones of the general formula (I) have herbicidal and growth-regulating properties.

Surprisingly, the substituted triazolinones of the general formula (I) according to the invention exhibit a considerably higher herbicidal potency against problem weeds than the nitrogen-heterocyclics known from the prior art, such as, for example, imidazolin-2-one-1-carboxylic acid isobutylamide or 1-phenyl-3-(3-trifluoromethylphenyl)-5-methyl-perhydropyrimidin-2-one, which are closely related compounds chemically and from the point of view of their action and moreover also have growth-regulating properties.

Formula (II) provides a general definition of the chloro(thio)carbonyl triazolinones required as starting substances for carrying out process (a) according to the invention. In this formula (II), R¹, R², X and Y preferably represent those radicals which have already been mentioned as preferred for these substituents in connection with the description of the substances of the formula (I) according to the invention.

The chloro(thio)carbonyl triazolinones of the formula (II) are not yet known.

They are obtained by a process in which triazolinones which are unsubstituted in the 1-position, of the formula (IV) ##STR109## in which R¹, R² and X have the abovementioned meaning, are reacted with (thio)phosgene of the formula (VI) ##STR110## in which Y has the abovementioned meaning, if appropriate in the presence of a diluent, such as, for example, toluene or acetonitrile, and if appropriate in the presence of an acid-binding agent, such as, for example, triethylamine, at temperatures between +20° C. and +150° C., and alternatively chloro(thio)carbonyl compounds of the formula (IIa) ##STR111## in which R¹, R⁵, R⁶ and Y have the abovementioned meaning, are also obtained by a process in which aminoguanidinium hydrochlorides of the formula (VII) ##STR112## in which R¹, R⁵ and R⁶ have the abovementioned meaning, are reacted with twice the molar excess of thio)phosgene of the formula (VI) ##STR113## in which Y has the abovementioned meaning, if appropriate in the presence of a diluent, such as, for example, toluene or acetonitrile, and if appropriate in the presence of an acid-binding agent, at temperatures between +20° C. and +150° C.

The aminoguanidinium hydrochlorides of the formula (VII) are obtained by a process analogous to known processes, for example by a procedure in which the generally known ureas of the formula (VIII) ##STR114## in which R¹, R⁵ and R⁶ have the abovementioned meaning, are initially reacted in a 1st stage with (thio)phosgene of the formula (VI) ##STR115## in which Y has the abovementioned meaning, if appropriate in the presence of a diluent, such as, for example, toluene or acetonitrile, at temperatures between 10° C and +150° C., and the formamidine hydrochlorides thus obtainable, of the formula (IX) ##STR116## in which R¹, R⁵ and R⁶ have the abovementioned meaning are reacted in a 2nd stage with hydrazine hydrate, if appropriate in the presence of a diluent, such as, for example, isopropanol or methylene chloride, at temperatures: between -10° C. and +60° C.

Perkin Trans. 1, 1059 1982!; Arzneimittel Forsch. 27, 343 1977!; Compt. Rend. 253, 1974 1961!; Bull. Soc. Chim. Fr. 1963, 144; and French Patent FR M 1,559 of 3.12.62). The known as well as the unknown compounds of the formula (IV) are obtained by a process analogous to known processes (compare, for example, J. org. Chem. 51, 1719 1986!; U.S. Pat. No. 4,098,896 and the preparation examples). Triazolinones which are unsubstituted in the 1-position, of the formula (IVa) ##STR117## in which R¹, R⁷ and X have the abovementioned meaning and m represents the number 1 or 2, are obtained from the corresponding compounds of the formula (IVb) ##STR118## in which R¹, R⁷ and X have the abovementioned meaning, in the generally known manner with customary oxidizing agents, for example by reaction with 3-chloroperbenzoic acid, if appropriate in the presence of a diluent, such as, for example, methylene chloride or acetonitrile, and if appropriate in the presence of a catalyst, such as, for example, ammonium molybdate, at temperatures between 0° C. and 40° C.

Formula (V) provides a general definition of the iso(thio)cyanates furthermore required as starting substances for carrying out process (b) according to the invention. In this formula (V), R⁴ and Y preferably represent those radicals which have already been mentioned as preferred for these substituents in connection with the description of the substances of the formula (I) according to the invention.

The iso(thio)cyanates are generally known compounds of organic chemistry (compare, for example, Saul Patai, "The Chemistry of Cyanates and their Thio derivatives," J. Wiley & Sons, New York 1977)

Possible diluents for carrying out process (a) according to the invention are the inert organic solvents.

The reaction is carried out and the reaction products are worked up and isolated by a process analogous to generally known processes.

Possible diluents for carrying out process (b) according to the invention are likewise inert organic solvents. The diluents mentioned for process (a) are preferably used.

If appropriate, process (b) according to the invention can be carried out in the presence of a basic reaction auxiliary.

The salts can be isolated as crystalline products--then if appropriate after concentration.

The active, compounds according to the invention can be used as defoliants, desiccants, agents for destroying broad-leaved plants and, especially, as weedkillers. By weeds, in the broadest sense, there are to be understood all plants which grow in locations where they are undesired. Whether the substances according to the invention act as total or selective herbicides depends essentially on the amount used.

The active compounds according to the invention can be used, for example, in connection with the following plants:

Dicotyledon weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranunculus and Taraxacum.

Dicotyledon cultures of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Cucurbita.

Monocotvledon weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus and Apera.

Monocotyledon cultures of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.

However, the use of the active compounds according to the invention is in no way restricted to. these genera, but also extends in the same manner to other plants.

The compounds are suitable, depending on the concentration, for the total combating of weeds, for example on industrial terrain and rail tracks, and on paths and squares with or without tree plantings. Equally, the compounds can be employed for combating weeds in perennial cultures, for example afforestations, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hop-fields, on lawn, turf and pasture-land, and for the selective combating of weeds in annual cultures.

In particular, the compounds of the formula (I) according to the invention are suitable for selectively combating monocotyledon and dicotyledon weeds in monocotyledon crops, either using the pre-emergence or the post-emergence method. They are markedly more effective than, for example, isocarbamid.

To a certain extent, the compounds according to the invention also show fungicidal action, for example against Pyricularia on rice.

The active compounds according to the invention moreover engage in the metabolism of the plants and can therefore be employed as growth regulators.

Experience to date of the mode of action of plant growth regulators has shown that an active compound can also exert several different actions on plants. The actions of the compounds depend essentially on the point in time at which they are used, relative to the stage of development of the plant, and on the amounts of active compound applied to the plants or their environment and the way in which the compounds are applied. In every case, growth regulators are intended to influence the crop plants in the particular manner desired.

The amount of Leaf on plants can be controlled, under the influence of growth regulators, so that defoliation of the plants at a desired point in time is achieved. Such defoliation is of great importance in the mechanical harvesting of cotton, but is also of interest for facilitating harvesting in other crops, such as, for example, in viticulture. Defoliation of the plants can also be carried out to lower the transpiration of plants before they are transplanted.

When applied in appropriate amounts, the active compounds according to the invention also exhibit an insecticidal, bactericidal and fungicidal activity and can be used, for example, for combating hygiene and pests of stored products or for combating fungal diseases in cereals and rice-growing, such as, for example, against the mildew of cereal causative organism (Erysiphe graminis) or against the rice spot disease causative organism (PyricuLaria oryzae). In this field of use, the active compounds according to the invention also show systemic properties, in addition to good protective properties.

Depending on their particular physical and/or chemical properties, the active compounds can be converted to the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, natural and synthetic materials impregnated with active compound, very fine capsules in polymeric substances and in coating compositions for seed, and furthermore in formulations used with burning equipment, such as fumigating cartridges, fumigating cans, fumigating coils and the Like, as well as ULV cold mist and warm mist formulations.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents.

In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxiide, as well as water.

As solid carriers there are suitable; for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly-disperse silica, alumina and silicates, as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example non-ionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates as well as albumen hydrolysis products; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose.

Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latexes, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Further additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dye-stuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

EXAMPLE 315 ##STR407## (Process (a'))

3.0 g (20,7 mmol) of 4-methyl-5-methylthio-2,4-dihydro-3H-1,2,4-triazol-3-one are dissolved in 60 ml of acetonitrile, and 7.0 g (29 mmol) of 2-methoxycarbonylphenylsulphonyl-isocyanate, dissolved in 20 ml of acetonitrile, are added to this solution with stirring. The reaction mixture is stirred at 20° C. for 6 hours. The product which is obtained in crystalline form is then isolated by filtration with suction.

This gives 6.0 g (75 % of theory) of 4-methyl-5-methylthio-2-(2-methoxycarbonyl-phenylsulphonyl-aminocarbonyl)-2,4-dihydro-3H-1,2,4-triazol-3-one of melting point 184° C.

EXAMPLE 316 ##STR408## (Process (b'))

1.7 g (11.2 mmol) of 1,8-diazabicyclo- 5,4,0!-undec-7-ene (DBU) and 2.7 g (11.2 mmol) of 2-trifluoromethoxybenzenesulphonamide are added to a solution of 3.0 g (11.3 mmol) of 4-amino-5-methylthio-2-phenoxycarbonyl-2,4-dihydro-3H-1,2,4-triazol-3-one in 60 ml of methylene chloride. The reaction mixture is stirred for 4 hours at 20° C., then washed twice with 1% strength hydrochloric acid and three times with water, dried with sodium sulphate, and filtered. The filtrate is concentrated, the residue is stirred with diethyl ether, and the product which is obtained in crystalline form is isolated by filtration with suction.

This gives 2,1 g (45 % of theory) of 4-amino-5-methylthio-2-(2-trifluoromethoxy-phenylsulphonyl-aminocarbonyl)-2,4-dihydro-3H-1,2,4-triazol-3-one 5 of melting point 136° C.

Starting substances of the formula (IIa) EXAMPLE (X-1) ##STR529## Step 1 ##STR530##

A solution of 175 g (2.4 mol) of methyl isothio-cyanate in 300 ml of diethyl ether is added to a solution of 250 g (2.4 mol) of ethyl hydrazinoformate, with stirring. The reaction mixture is stirred for 12 hours at 20° C. and then cooled to about 10° C., and the product which is obtained in crystalline form is isolated by filtration with suction. This give 404 g (95% of theory) of 4-methyl-1-ethoxycarbonylthiosemicarbazide of melting point 130° C.

The following are obtained analogously: 4-ethyl-1-methoxycarbonyl-thiosemicarbazide (melting point: 142° C.); 4-propyl-1-methoxycarbonyl-thiosemicarbazide (melting point: 117° C. 4-cyclopropyl-1-methoxycarbonyl-thiosemicarbazide (melting point: 148° C.); 4-allyl-1-methoxycarbonyl-thiosemicarbazide (melting point: 151° C.); 4-dimethylamino-1-methoxycabonyl-thiosemicarbazide (melting point: 144° C.).

Step 2 ##STR531##

A mixture of 10.0 g (56.5 mmol) of 4-methyl-1-ethoxycarbonyl-thiosemicarbazide (cf. Step 1), 4.0 g (29 mmol) of potassium carbonate and 80 ml of ethanol is refluxed until the evolution of gas has ceased (about 3 hours). When the mixture is cold, it is concentrated, the residue is stirred with 50 ml of methylene chloride, and the product, which has remained undissolved, is isolated by filtration with suction.

This give 9.2 g (96% of theory) of the potassium salt of 5-mercapto-4-methyl-2,4-dihydro-3H-1,2,4-triazol-3-one (melting point >230° C.).

The potassium salts of 5-mercapto-4-ethyl-2,4-dihydro-3H-1,2,4-triazol-3-one, 5-mercapto-4-propyl-2,4-dihydro-3H-1,2,4-triazol-3-one, 5-mercapto-4-cyclopropyl-2,4-dihydro-3H-1,2,4-triazol-3-one, and 5-mercapto-4-allyl-2,4-dihydro-3H-1,2,4-triazol-3-one, and 5-mercapto-4-dimethylamino-2,4-dihydro-3H-1,2,4-triazol-3-one, all of which melt above 230° C. are obtained analogously.

Step 3 ##STR532##

A mixture of 4.0 g (23.7 mmol) of the potassium salt of 5-mercapto-4-methyl-2,4-dihydro-3H-1,2,4-triazol-3-one (cf. Step 2), 4.1 g (28.9 mmol) of methyl iodide and 80 ml of methanol is stirred for 12 hours at 20° C. The mixture is then concentrated, the residue is stirred with methylene chloride, and the potassium iodide, which has remained undissolved, is separated off by filtration. The filtrate is concentrated, the residue is stirred with 500 ml of diethyl ether/petroleum ether (1:1 by vol.), and the product which has been obtained in crystalline fromis isolated by filtration with suction.

This gives 3.4 g (99% of theory) of 4-methyl-5-methylthio-2,4-dihydro-3H-1,2,4-triazol-3-one of melting point 97° C.

22.1 g (0.141 mol) of phenyl chloroformate are added to a mixture of 20.0 g (0.137 mol) of 4-amino-5-methylthio-2,4-dihydro-3H-1,2,4-triazol-3-one, 5.6 g (0.141 mol) of sodium hydroxide, 0.2 g of tetrabutylammonium bromide and 200 ml of methylene chloride/water (1:1, by vol.), with vigorous stirring. The reaction mixture is stirred for 12 hours at 20° C., and the product which is obtained in crystalline form is isolated by filtration with suction. This gives 34.8 g (95% of theory) of 4-amino-5-methylthio-2-phenoxycarobnyl-2,4-dihyro -3H-1,2,4-traizol-3-one of melting point 211° C.
